Purpose: The purpose of this study was to investigate the current status and satisfaction of dental CAD/CAM system. Methods: A survey of dental technicians was conducted and a total of 353 responses were used for analysis. The satisfaction difference according to career was analyzed by ANOVA and tukey HSD (α = .05). Results: Satisfaction with the design program was 3.64 ± .86, the highest among all items. On the other hand, the satisfaction with price was 2.75 ± 1.02, which was the lowest. The difference according to career was statistically significant in the following items. Frequent breakdown, single crown margin, bridge crown margin, retentivity, price, A/S, equipment training (p<.05). Conclusion: As the materials applied to dental CAD/CAM are expanding and the types of prostheses are diversified, the use rate of CAD/CAM is continuously increasing. The dental CAD/CAM system will need to be improved in a way that will satisfy all patients, dentists and dental technicians.

The goal of this study is to scrutinize the impact of individual online convenience dimensions on mobile banking acceptance and use in Mongolia. A total of 211 valid responses were collected from Mongolian university students who currently use mobile banking application services from local banks. The SmartPLS 3.3 software was used to conduct the confirmatory factor analysis and test the hypotheses. Using structural equation modelling, this research discovered that access convenience, transaction convenience, and possession/post-possession convenience are the main constructs related to the adoption of mobile banking services. Perceived innovation showed a significant positive effect on the adoption of mobile banking technologies. Through practical and theoretical implications, this research aims to assist mobile banking service channels of local and international banks in Mongolia. Identifying which online convenience dimensions impact the adoption and use of mobile banking will contribute to the adoption of competitive strategies for financial institutions and banks.

This study aims to empirically investigate how personalized and socialized mobile media impacts on users' acceptance of mobile advertising, given the consideration of users' mobile possession attachment. For this, the current study used focus group interview and surveyed mobile users. Interestingly, the findings reveal that personalized and socialized mobile characteristicssignificantly affect users' acceptance of mobile ads. That is to say, users' personalized mobile characteristics play an important role in either awareness of mobile ads or exposure to mobile ads.

The purpose of this study was to evaluate the status of sanitary management based on HACCP. The surveys which were on various aspects of general characteristics, food handling practice, personal sanitation, equipment sanitation, and equipment possession were carried out using questionnaires for 146 business and industry foodservice operations in Taegu and Kyungpook areas. The results of this study were summarized as follows. Forty-nine percent of surveyed foodservice operations was in Taegu, 51% in Kyungpook and 69.2% in direct foodservice operations and 28.1% in contracted foodservice operations. Seventy-eight percent of foodservice operations replied that they have done only basic sanitary management, while 13% surveyed stated that they were implementing HACCP. Food handling practice and personal sanitation were significantly better in Kyungpook area than in Taegu. Significantly high levels in food handling practice, personal sanitation, equipment sanitation, and equipment possession were seen in foodservice operations which had more than 1,000 meal served than those which had less than 1,000 meals served. According to the results of food handling practice, in items of food-temperature measurement during receiving, cooking, holding after cooking, and reheating, foodservice operations showed very low scores below the average. All foodservice operations presented good scores in the parts of personal and equipment sanitation. In equipment possession, sterilizing systems were generally not enough, dishwasher and sterilizing facilities of contracted foodservice operation showed significantly high scores. Therefore, the business and industry foodservice operations will have to pay special attention to temperature management in the foodservice production process as the first step to implement of HACCP.

Cloud storage as a service provides high scalability and availability as per need of user, without large investment on infrastructure. However, data security risks, such as confidentiality, privacy, and integrity of the outsourced data are associated with the cloud-computing model. Over the year's techniques such as, remote data checking (RDC), data integrity protection (DIP), provable data possession (PDP), proof of storage (POS), and proof of retrievability (POR) have been devised to frequently and securely check the integrity of outsourced data. In this paper, we improve the efficiency of PDP scheme, in terms of computation, storage, and communication cost for large data archives. By utilizing the capabilities of JAR and ZIP technology, the cost of searching the metadata in proof generation process is reduced from O(n) to O(1). Moreover, due to direct access to metadata, disk I/O cost is reduced and resulting in 50 to 60 time faster proof generation for large datasets. Furthermore, our proposed scheme achieved 50% reduction in storage size of data and respective metadata that result in providing storage and communication efficiency.

This research was conducted to investigate methods to strengthen the apartment community from the territoriality point of view. In order to achieve this goal, first of all the concept and the structure of territoriality are studied through articles and literature reviews to ensure a full understanding of the community strengthening-related plan elements suggested in the previous research. The study is then divided into the categories of semi-private territory and semi-public territory to pursue analysis based on the issues related to strengthening community such as possession, proximity, defense, boundary-regulation, and personalization in case by case studies. The results of case studies are as follows: in the case of possession with psychological concept of possession, the extension of private space and exclusive space are suggested. And for the concept of proximity, that is, the physical and psychological distance for sense of the same nature, increased opportunity of meeting the residents in the same building or same area are suggested And for the psychological proximity, familiar design and facilities for meeting and exchange-related methods are shown. For the case of indirect defense in defense concept, the methods related to monitoring and supervising facilities for protection are found. For the boundary-regulations, it is based on the concepts of physical and psychological borderlines; walls either vertical or horizontal, or such obstacle-related methods are suggested for the physical borderline, and space structure and symbols-related methods are found for psychological borderline. Finally, for the case of personalization which is related to the expression of identity, design-related methods are suggested.

Recently, one of the issues to be discussed from the viewpoint of product management in National R&D Programs is about the management of intellectual property produced by joint research and development. According to existing legislative system, the main R&D institute and collaborative enterprise own the patent produced by joint R&D activities together at the rate of investment. But, there are many discussions if that is right in legal principles and in substance. Patents by Cooperative National R&D Programs are very different from common patents because of its characteristics and have scheme controlled complexly by related laws and ordinances. This paper aims to review the legal theory on the possession and utilization of patents produced by Cooperative National R&D Programs, and to try to find out the improvement of existing legislative system. For this purpose, after looking into the meaning and the legal system of Cooperative National R&D Programs, and examining the ruling theory on the possession and utilization of co-invented patent, finally research the problems and improvement of existing related legislative system.
